TCT-871 Leveraging Preparatory Balloon Aortic Valvuloplasty (BAV) During TAVI for Improved Valve Sizing – A simple way to reduce Paravalvular Aortic Regurgitation (PAR)?!

Valve-size selection for TAVI is based on annular measurements by echocardiography or CT. Still, relevant PAR with negative impact on survival is common(20%). We sought to evaluate whether supraaortic angiography during BAV may provide improved sizing([figure][1]). ![Figure][2] Data of 167
